Thanks Ted,

Dunno what ShoutCast/IceCast are using. Looking
through the conf tells me this:

; MaxUser.  
; The maximum number of simultaneous listeners
; Compute a reasonable value for your available 
; upstream bandwidth (i.e. if you have 256kbps upload
; DSL, and want to broadcast at 24kbps, you would
; choose 256kbps/24kbps=10 maximum listeners.)  
; Setting this value higher only wastes RAM and screws
; up your broadcast when more people connect than you 
; can support.

Sounds more like unicast to me - but then, I'm a
complete n00b when it comes to this stuff ;)

/me is off looking for more coffee...
